Rapeseed oil is harmful. Beneficial properties of rapeseed oil

07.03.17

Until the end of the 1980s, rapeseed was used only for technical purposes. Now they have learned to make a healthy food product from it - rapeseed oil.

This is a great success achieved thanks to new advances in biochemistry, molecular biology, breeding, and oil purification technologies.

Our publication is about the dangers and benefits of rapeseed oil for health, how to take it and where to use it.

How to choose

When we say “high-quality rapeseed oil,” we mean “canola.” Canola (CANadion Oil Low Acid) is the common name for low erucic rapeseed varieties. For the first time, such varieties of rapeseed were bred by a Canadian scientist, hence the name.

For comparison: technical rapeseed contains up to 60% erucic acid (hereinafter referred to as EC for brevity), and canola – from 0 to 5%.

Why was it so important to achieve low scores? Through toxicological studies it was found that EC does not oxidize itself well and prevents other acids from doing so..

A large number of toxins first accumulate in the heart, and then in other organs. Serious pathologies appear, including necrosis. Thrombocytopathy may occur.

Although this fact has been studied in animals, the concerns still remain serious in humans.

In addition to EC, the raw materials contain other toxic substances - isocyanates(thioglycoside derivatives). They are found up to 45% (with an acceptable rate of 3%).

They are dangerous because they contain sulfur, inhibit the growth of young organisms, cause irreversible changes in the thyroid gland, enterocolitis. They have a bitter taste and a specific smell.

Do not forget about toxic volatile ethers, harmful pigments.

Therefore, the purification technology necessarily includes sulfuric acid refining and bleaching with adsorbents.

And to remove fatty acids, conventional refining is additionally used.

The highest quality canola oil (canola) is usually sold in dark glass containers.

The label indicates that this is a food product, there must be marks of quality, expiration date, and the EC content is indicated (the permissible norm is 5%).

Color - golden yellow or slightly greenish, there should be no sediment.

Chemical composition, calorie content, nutritional value, glycemic index

Beneficial features

Everyone can appreciate the product. Advantages:

• easy to digest;
• has an optimal ratio of physiologically important acids for the body;
• is a unique source of phytoestrogen, which is identical in composition to the female hormone estradiol;
• It has a pleasant nutty flavor.

The “Live Healthy!” program will tell you about the beneficial properties and contraindications of rapeseed oil:

Why it's useful

Polyunsaturated acids (Omega-6 and Omega-3) are in the only ratio that is true for health: 1:2. And this is the correct functioning of the brain, heart, reduction of inflammation, prevention of tumors.

Harmful saturated fatty and trans fatty acids make up a very low percentage, which reduces the risk of cholesterol plaques on the walls of blood vessels.

The manufacturer enriches the product with tocopherol(form of vitamin E content). It, like all antioxidants, is a powerful stimulator of regenerative processes. Improves the health of our skin, nails and hair.

For pregnant and lactating women

Is rapeseed oil good for expectant mothers? Yes. It contains a natural analogue of the female hormone - estradiol..

This hormone affects a woman’s mood, attractiveness, stamina, and reproductive function. Responsible for preserving the fetus and blood clotting, which is important in preparation for childbirth.

A group of French scientists found that in those regions where women constantly consume this product, there is a significantly lower percentage of breast cancer.

So nursing mothers do not have to worry for themselves, and for their children too.

For children

Rapeseed oil is safe and is included in many infant formulas..

It can perfectly complement a regular children's diet, since it is light, rarely causes allergies, has a good effect on brain activity. Why not experiment?

You just need to agree with your pediatrician on the daily dose of consumption: It is different for each age category.

For the elderly

It's gentle product for the digestive system of older people. Therefore, it functions as a supplier of essential acids.

Animal fats and milk should be kept to a minimum at this stage of life. They contain too much cholesterol and saturated fat.

In old age, only refined food is useful in the form of salad dressings. Frying on it is strictly prohibited.

Rapeseed is a herbaceous plant, the cultivation of which began more than two thousand years ago. During this period, people learned to extract oil from it, which in its taste and healing qualities is somewhat reminiscent of olive oil. There is no consensus regarding what can be considered the plant’s homeland. But this is definitely the Mediterranean coast or India. You need to start studying the negative and positive properties of oil with the chemical composition. Let's get started!

Composition and features of rapeseed oil

The most valuable qualities are determined by the inclusion of the following substances: vitamin F, unsaturated fatty acids, carotenoids. Omega acids cannot be produced independently by the human body, but must be present in the diet of every person.

The presented complex of substances supports the functioning of the most important systems and organs, controls water balance, fat and carbohydrate metabolism. Omega acids are necessary to prevent atherosclerosis and other pathologies of this type.

In addition, the composition contains tocopherol and vitamin E. It is responsible for strengthening the immune system, improving the functioning of the central nervous system, and maintaining the beauty of hair and nails. Vitamin E, of which the oil contains as much as 30% of the permissible daily value, is also an antioxidant substance that removes toxins and heavy metal salts from the body.

Of the mineral substances, mention should be made of the most valuable magnesium, zinc, copper, calcium, phosphorus, and potassium. Also, rapeseed is not deprived of B-group vitamins, retinol, vitamin D, vitamin K. Each substance presented has its own beneficial properties.

For example, retinol is otherwise called vitamin A. It improves vision along with carotenoids, therefore it is used to treat eye diseases. Vitamin D compacts bone tissue, promotes rapid tissue regeneration, and protects the skin from damage due to the formation of an invisible film.

Vitamins included in group B affect the psycho-emotional environment of a person. These substances help cope with strong mental or physical activity, restoring energy levels. Vitamin K is known to everyone as a means of increasing blood clotting and quality.

Rapeseed oil production

Today, there are many variations of the raw materials presented, suitable for use for technical, cosmetic and culinary purposes. There is even a plant variety that is cultivated for the purpose of further production of bio-fuel.

Thanks to the machinations of breeders, the study and production of rapeseed oil for culinary purposes has become possible and easy. But in order not to be mistaken in all the variety of products, you need to buy the Canola variety.

To obtain exclusively useful raw materials, production is carried out by cold pressing. But sometimes by freezing, hydration, or other methods.

Rapeseed does not grow wild in nature. But it has been cultivated for more than 5 thousand years. For a long time, the scope of application of the plant was limited to the technical field. Rapeseed oil has been used to produce biofuel, soap; in the textile and leather industry.

Unrefined rapeseed oil contains thioglucosides and erucic acid (more than 60%). These are substances hazardous to health: the human enzyme system is not able to utilize them. They accumulate in body tissues and cause harm.

Only mutant varieties of rapeseed, in whose oil the content of erucic acid is minimal, is suitable for food purposes. According to GOST 8988-2002, only unrefined first-grade rapeseed oil or refined, non-deodorized rapeseed oil, in which the concentration of erucic acid is less than 5% and thioglucosides - less than 3%, is allowed for food. If these conditions are met, the product will not cause harm.

Rapeseed oil, like any vegetable oil (sunflower, olive, corn), is high in calories. The product is 99% fat. Let's highlight the most useful of them:

• saturated fatty acids (10%);
• unsaturated fatty acids (33%);
• monounsaturated (oleic acid);
• polyunsaturated (linolenic, linoleic acids);
• phospholipids, etc.

The benefit of the product also depends on vitamin and mineral composition:

• vitamin E (tocopherols);
• carotenoids;
• B vitamins;
• vitamin D;
• phosphorus;
• zinc;
• copper;
• magnesium, etc.

Sometimes rapeseed extract is called “Russian olive oil.” The composition of these products is similar, the benefits are enormous.

Application, harm and benefits of rapeseed oil

Benefits of rapeseed oil

In addition to its high calorie content, the benefit of rapeseed oil is that it contains Omega 3 and Omega 6 fatty acids, the proportions of which are ideal for the human body. Omega 3 supports normal human growth and development, is important for good skin and proper kidney function, and is vital for normal eye and brain function.

The oleic acid contained in the oil is an excellent component of dietary and therapeutic nutrition.

Linoleic acid in oil is not only a preventive agent for cardiovascular diseases, but also helps improve their condition.

A tablespoon of this product provides a person with the daily requirement of vitamin E, which is a natural antioxidant. Regular use of it, thanks to a phytohormone identical to that of women, recently found in it, promotes the conception of a child and makes a woman attractive.

Harm of rapeseed oil to the body

Only oil that is unrefined and made from low-quality seeds causes harm to the human body. This is explained by the presence in it of residual components of erucic acid, which is harmful to all mammals because it is not excreted, but is deposited in the tissues. The presence of erucic acid in the human body is fraught with a slowdown in growth and development of reproductive function, and disruption of the functioning of some internal organs. And therefore, even the relative cheapness of production did not make it possible to squeeze it for food purposes. But almost fifty years ago, a rapeseed variety was developed in Canada, the amount of erucic acid in which did not exceed two percent. This prompted industrialists to begin producing a new food product. Rapeseed oil began to be added to butters and margarines.

Contraindications for use

Rapeseed oil: benefit or harm?

Rapeseed oil gained wide recognition in the 80s of the twentieth century, when it became possible to reduce the level of erucic acid in rapeseed, a rather harmful product. At the moment, this oil is considered one of the most popular in Europe, as it has a balanced composition (it is in third place in demand).

Rapeseed does not occur in the wild. It is cultivated in countries where there are favorable climatic conditions for its growth - such as China, India, Canada, and Western and Central European countries. Its main producers are the Czech Republic, Poland and China, which harvest up to half of the world's rapeseed harvest.

Unlike other oils, rapeseed oil has an unusual flavor, very similar to a nutty one, which is favorable for creating delicious dishes. In most countries, it is used to prepare various sauces and salad dressings, although it can also be used for frying.

Rapeseed oil is quite balanced: it contains unsaturated fatty acids (66%), polyunsaturated fatty acids (27%), saturated fatty acids (6%). It contains less saturated fatty acids than other vegetable oils. Rapeseed oil contains vitamin E and carotenoids.

As you can see, the percentage of polyunsaturated fatty acids (Omega-3 and Omega-6) in this product is quite high, just like olive oil. These substances help reduce cholesterol levels in the blood and strengthen the walls of blood vessels, and also reduce the risk of blood clots. Rapeseed oil is considered a product useful when following an anti-sclerotic diet. Many European doctors advise using it instead of olive oil for salad dressings. The main difference between these oils and each other is that the production of oil from olives is a rather expensive process, and therefore the price of such a product is significantly higher. Meanwhile, in terms of taste, rapeseed oil is in no way inferior to olive oil.

Rapeseed oil, like all other types of oils, should be stored in a cool, dark place so that its beneficial properties are not lost. In such conditions, it will stand for quite a long time without deteriorating or changing color or smell.

Currently, rapeseed oil, the harm of which, thanks to modern technologies, has been practically reduced to zero, is considered a complete food product. But several decades ago, when the content of erucic acid in rapeseed was quite high, this oil was used only for industrial purposes (in particular, for the production of soap and drying oil) and was unsuitable for consumption. Nowadays, the percentage of this acid has been reduced to almost zero, less than 0.2%, which does not affect the human body in any way. And soon in new varieties of rapeseed they promise to completely eliminate erucic acid and reduce the percentage of fatty acids. Therefore, rapeseed oil, the benefits of which have been proven above, is gaining popularity all over the world.

In this regard, rapeseed oil outperforms its peers, leaving behind the most common product in Russia – sunflower oil. After all, only the domestic market is saturated with this sunflower seed product; palm oil and flaxseed oil with rapeseed have been used all over the world for a long time - they are more beneficial for health.

Characteristics: What are the benefits of rapeseed oil?

Based on the facts confirming how widespread rapeseed oil is in the global industry, we can talk about its beneficial characteristics. It may not be comparable in usefulness to olive or sea buckthorn oil, but nevertheless, rapeseed oil can boast the following properties:

1. First of all, rapeseed oil is rich in vitamin E and polyunsaturated fatty acids. Needless to say, these elements indicate the oil’s ability to support the body’s immune forces, ensure proper functioning of the heart, blood vessels, and brain, and also reduce the risk of heart attacks, strokes, hypertension and coronary heart disease.

2. Rapeseed oil also contains a fairly high percentage of a female hormone called estradiol. The level of this hormone increases naturally with the onset of ovulation. A woman’s skin becomes radiant and clean, and her hair becomes elastic and strong.

3. Thanks to this vitamin complex, the risk of breast cancer in girls tends to zero.

4. Do you want to lose weight faster? Rapeseed oil will be your assistant for this. It breaks down fats, lowers cholesterol levels, and significantly speeds up metabolism. It can be eaten as a complement to salads and other dishes.

5. Rapeseed oil is very often used as an element of any diet. It is rarely used independently. For example, it is added to kefir or protein diets, and is also used as a dietary supplement during the treatment of diseases of the gastrointestinal tract.

6. On top of that, rapeseed oil will be appropriate in masks for the face or hair. It heals small wounds, scratches, burns, strengthens the hair structure, and perfectly moisturizes the skin.

Contraindications for use and potential harm of rapeseed oil

Rapeseed oil must be refined, since the unrefined liquid may contain a high percentage of erucic acid. It is not considered too beneficial for the animal or human body, since it may well slow down the process of growth and development, as well as puberty. In addition, due to the high percentage of erucic acid in rapeseed, a healthy person may develop problems in the cardiovascular system, problems with the liver and kidneys. When purchasing rapeseed oil yourself, be sure to pay attention to erucic acid levels: normally they should not be more than 0.6%.

Of course, it is also worth mentioning individual intolerance to various types of oils, including rapeseed. Allergy sufferers should not eat this product, because there is a high risk of swelling, suffocation, rashes and itching.

At the same time, women with biliary tract diseases, pancreatitis and cholecystitis should not eat salads, first or second courses containing rapeseed oil. Moreover, those suffering from chronic diarrhea or hepatitis are prohibited from using rapeseed oil, because in this case it has a negative effect on the liver.

It is worth considering, among other things, some toxicity of rapeseed oil, which manifests itself during its heating. That is why nutritionists do not recommend eating too much of it, much less frying any food with it.

Rapeseed is a cultivated plant, from the seeds of which a valuable plant product is obtained. The benefits and harms of rapeseed oil have been well studied, which leads to its use in cooking, cosmetology, traditional and folk medicine.

A little history

The herbaceous plant rapeseed began to be cultivated 1500-2000 years ago. Until now, its homeland is not exactly known: some believe that it is Northern India, others are convinced that it is the Mediterranean. Another name for rapeseed oil is “northern olive”, or “northern olive”. After all, in terms of its taste and beneficial composition, the herbal remedy is close to olive oil, but costs a little less.

Initially, the natural product was used only for technical purposes. Rapeseed oil was produced for the automotive industry as a lubricant, and was also used in soap making, textiles, and for indoor lighting. It was not consumed as food due to the high percentage of a harmful compound - erucic acid. This substance is considered a poison: the human body is not able to break it down, which leads to the deposition of acid in the body and provokes the occurrence of certain diseases.

In the early 70s, breeders from Canada developed a new variety of rapeseed, in which the content of harmful compounds was reduced to 2%. After this, the valuable liquid began to be used for food.

Nowadays, the popularity of rapeseed oil is increasing. The product is widely known in Europe and the USA, but in Russia the oily plant is treated with caution and caution. The culture became widespread due to the low cost of production and its waste-free nature. Let's find out whether rapeseed oil is harmful or beneficial.

Valuable composition

Rapeseed oil is a yellowish or brownish liquid. It tastes like olive oil and has a nutty smell. The calorie content of the product is high and amounts to 900 kcal per 100 g. Its beneficial properties are due to the following components in its composition.

• Polyunsaturated fatty acids are Omega-3 and Omega-6, called vitamin F. These acids are not produced by the body itself, but are necessary for its proper functioning. The complex supports fat metabolism, reduces the amount of bad cholesterol in the blood, therefore, with a sufficient supply of these fatty acids in the body, the risk of developing atherosclerosis and diseases of the cardiovascular system is significantly reduced. They also help strengthen the nervous system and improve immunity.
• Vitamin E is a natural antioxidant needed to preserve beauty, youth and health. Deficiency of this substance negatively affects the condition of the reproductive system, hair, nails and skin.
• Tocopherols, carotenoids.
• Vitamins A, D, K, group B.
• Microelements - zinc, phosphorus, calcium, magnesium, copper.

This is interesting!

Vitamin E in 1 tbsp. l. There is a lot of natural healing agent - 30% of the body's daily needs.

B vitamins are responsible for the proper functioning of the nervous system and affect the functioning of the immune system. They are necessary under high stress, emotional and mental, during stress and during chronic diseases. Vitamin A keeps vision normal and is responsible for immunity; vitamin D helps skin wounds, abrasions and scratches heal faster, and protects against damage to the skin. Vitamin K is responsible for blood clotting processes.

Benefits of using the product

Compositions based on it soften, moisturize and nourish the skin. The valuable liquid brings particular benefits to tired and dry skin. It is also practiced to use the product to beauty curls, giving them shine and softness.

Here are common recipes for hair and skin.

• Nourishing hair mask

Rub rapeseed oil into the hair roots and scalp with light massaging movements, cover the hair with a cap, and put a towel on top. Leave the mask on for half an hour, then remove with warm water and shampoo. Sessions are held twice a month.

• Anti-dandruff mask

Add rapeseed oil to ready-made store-bought shampoo (10 ml of oil per 100 ml of product). Wash your hair with this solution. As a result, the scalp will become soft and moisturized, and dandruff will disappear.

Use in cooking

Rapeseed oil is excellent for dressing salads, first and second courses, and only when cold or slightly heated in a water bath.

A feature of the cultivated plant oil is the release of toxic substances when heated. Therefore, it is worth using it in cooking, but not frying food with it.

Selecting a valuable product

For those wishing to purchase rapeseed oil, we present the main criteria for choosing the right product.

• If the liquid is opaque or there is sediment at the bottom of the container, you should avoid purchasing oil. This indicates the low quality of the raw materials and their unsuitability for consumption.
• Carefully study the label on the bottle: the concentration of erucic acid should be no more than 0.5%.
• You need to choose only oil that has gone through all stages of processing - refined.
• If the packaging says that the product is hydrogenated, then you should not purchase the product.
• The normal color of the oily liquid is golden to light brown. The pale shade of the product indicates its low quality.

The oil of the cultivated plant should be stored in a glass container with a tight-fitting lid. The container must be placed in a cool, dark place without the risk of direct sunlight. This way, all the valuable properties of racial oil will be preserved for as long as possible.

Potential harm and contraindications

Unrefined rapeseed oil can be dangerous to the body. The crude liquid contains large quantities of erucic acid. It accumulates in tissues and can lead to unpleasant consequences:

• problems with the heart;
• deterioration of liver activity, in worst cases – to the development of cirrhosis;
• growth retardation, disturbances in the development of the reproductive system.

It is important to follow the norm in the use of rapeseed oil. Any product in unlimited quantities can negatively affect the functioning of the body.

Contraindications to consuming oil are:

• acute stage of cholelithiasis;
• period of exacerbation of hepatitis in chronic form;
• cholecystitis;
• personal intolerance to components.

Rapeseed oil should be introduced into the diet with caution due to the possibility of developing allergic reactions to the new product (suffocation, swelling, itching and rashes). If you are prone to diarrhea, it is better to avoid using a natural remedy.

The benefits of rapeseed oil significantly outweigh the possible harm. When consumed in small quantities, the golden liquid will saturate the body with useful compounds and strengthen its protective functions.
